Seat Suspensions Systems
for Upholstered Furniture
Mayo Sinuous Springs
also called “no-sag springs”
Mayo uses a double roll of sinuous springs on the inside edge to minimize the “roll toward
the arm” effect. Seat springs are connected by spring steel stabilizer wire in two places.
These stabilizer wires run inside arm to inside arm and help distribute weight across the
surface of the seat spring system.

Some manufacturers - in an effort
to save money - will elect to use
“big loop” springs. However, all
the resiliency in a sinuous spring
is contained in the convolutions
(loops) of the spring. Fewer loops
mean less bounce back.
Big loop springs use less steel,
therefore less cost. Mayo does not
use big loop seat springs.
Mayo Drop-In Coil Springs
Mayo uses a high quality drop in coil spring system that represents the latest advancements in coil
spring seating. Coil springs are unitized with an oil-tempered spring steel grid. This grid top eliminates noisy top support systems found in other spring assemblies.

Genuine 8-way Hand-tied Springs
This is the real thing ... “hour shaped” coils individually
tied in 8 places across the top of each coil

“Fake” 8-way Hand-tied Springs
This is an actual ad from a trade
magazine showing a drop-in coil
ready to be placed in the product.
An example of a “ready- to-go”
drop-in coil unit that has been
“rigged as 8 way hand-tied”
so that it can be marketed as
a 8-way hand-tied coil unit.
It’s true, coils have been tied
in 8 locations of each spring
- but, clearly, this effort adds
nothing to the quality of the
product.
“Fake” 8-way hand-tied coil system in use.
The hand-tied twine contributes nothing
to the quality of this seat suspension. It
does however permit the manufacturer to
advertise “8-way hand-tied” seating.
Miscellaneous Seating Systems
This is an example of elastic
webbing. Elastic webbing is
sometimes found in leather
seating systems and furniture
pieces that are oddly shaped
and difficult to fit with sinuous
or coil spring seating systems.

using
“marshall
coils.”
